RESUMEN
<b>Introduction:</b> Computer-based interactive techniques are becoming an important tool in medical education. One of the important benefits of the use of telemedicine in surgical training is the reduction of the number of people in the operating room. As shown in the studies, this can lead i.a. to the reduction in the risk of surgical site infections.<b>Aim:</b> The aim of this survey as held among fifth-year medical students at three academic centers was to assess the usefulness and effectiveness of telemedicine as a surgery-teaching tool.<b>Material and methods:</b> A transmission of a surgical procedure was carried out by each of the three participating centers according to a previously prepared schedule. Each transmission was preceded by the diagnostics, indications, and the course of the surgical procedure being discussed by the facilitator physician who also coordinated the transmission throughout the procedure. After the class, students received anonymous surveys consisting of fourteen questions as per the attached protocol so as to evaluate the class using the rating scale of 1 (the lowest rating) through 5 (the highest rating). The survey assessed the educational value (the knowledge acquired from the class), the form (interactivity, facilitator complicity), and the usefulness of the class for overall surgical education.<b>Results:</b> The survey was completed by 232 students, with 95% of respondents rating the usefulness of telemedicine classes in surgical education as very good or good. As many as 97% of students declared that the transmission had been a good or a very good tool in terms of delivery or adding to their knowledge of topographical anatomy and basic aspects of surgical technique. Higher ratings were given to the usefulness of comments and remarks by the facilitating physician (96% of very good or good ratings) who had been watching the procedure along with the students as compared to those provided by the operating physician (81%).<b>Discussion:</b> The use of telemedicine-based teaching models in surgical education facilitates a better view of the operating field for the students, greater accessibility of educational content delivered simultaneously to multiple groups of students, increased safety of the surgical procedure by reducing the number of people in the operating room as well as reduced burden on the operating physician (thanks to the introduction of class facilitator).<b>Conclusions:</b> In our opinion, the advantages of the presented teaching model are: better view (particularly in case of open procedures), ability to pinpoint surgical field structures (on the participants' and operator's monitors), absence of additional people (students) in the operating room (increasing the safety of the procedure and reducing the risk of surgical site infections) and the ability to go back to recorded operations and perform various types of educational analyses.

Despite continuous medical advancements, traumatic brain injury (TBI) remains a leading cause of death and disability worldwide. Consequently, there is a pursuit for biomarkers that allow non-invasive monitoring of patients after cranial trauma, potentially improving clinical management and reducing complications and mortality. Aquaporins (AQPs), which are crucial for transmembrane water transport, may be significant in this context. This study included 48 patients, with 27 having acute (aSDH) and 21 having chronic subdural hematoma (cSDH). Blood plasma samples were collected from the participants at three intervals: the first sample before surgery, the second at 15 h, and the third at 30 h post-surgery. Plasma concentrations of AQP1, AQP2, AQP4, and AQP9 were determined using the sandwich ELISA technique. CT scans were performed on all patients pre- and post-surgery. Correlations between variables were examined using Spearman's nonparametric rank correlation coefficient. A strong correlation was found between aquaporin 2 levels and the volume of chronic subdural hematoma and midline shift. However, no significant link was found between aquaporin levels (AQP1, AQP2, AQP4, and AQP9) before and after surgery for acute subdural hematoma, nor for AQP1, AQP4, and AQP9 after surgery for chronic subdural hematoma. In the chronic SDH group, AQP2 plasma concentration negatively correlated with the midline shift measured before surgery (Spearman's ρ -0.54; p = 0.017) and positively with hematoma volume change between baseline and 30 h post-surgery (Spearman's ρ 0.627; p = 0.007). No statistically significant correlation was found between aquaporin plasma levels and hematoma volume for AQP1, AQP2, AQP4, and AQP9 in patients with acute SDH. There is a correlation between chronic subdural hematoma volume, measured radiologically, and serum AQP2 concentration, highlighting aquaporins' potential as clinical biomarkers.

Contemporary literature lacks examples of intradural, extramedullary spinal glomangiomas. Moreover, glomus tumors in general are exceedingly rare among benign spinal tumors and are mostly located within epidural space or within intervertebral foramen, and only a few cases have been documented to date. This report provides a detailed analysis of the clinical presentation, imaging characteristics, surgical intervention, and pathological findings of a 45-year-old patient experiencing progressive locomotor deterioration. The tumor was surgically excised, and subsequent histological examination identified it as a representative of glomus tumors-a glomangioma. Notably, this represents a unique case as it was the first example of such a tumor being discovered intradurally. Radical surgical excision remains the modality of choice in most benign spinal tumors of this localization. Although the malignant transformation of glomus tumors within the spine has not been documented thus far, cases have arisen in other areas. Consequently, we will investigate potential oncological treatments for cases with malignant potential and highlight advancements in surgical techniques for benign intradural spinal tumors.

INTRODUCTION: Traumatic injuries are a significant global health concern, with profound medical and socioeconomic impacts. This study explores the patterns of trauma-related hospitalizations in the Lublin Province of Poland, with a particular focus on the periods before and during the COVID-19 pandemic. AIM OF THE STUDY: The primary aim of this research was to assess the trends in trauma admissions, the average length of hospital stays, and mortality rates associated with different types of injuries, comparing urban and rural settings over two distinct time periods: 2018-2019 and 2020-2021. METHODS: This descriptive study analyzed trauma admission data from 35 hospitals in the Lublin Province, as recorded in the National General Hospital Morbidity Study (NGHMS). Patients were classified based on the International Classification of Diseases Revision 10 (ICD-10) codes. The data were compared for two periods: an 11-week span during the initial COVID-19 lockdown in 2020 and the equivalent period in 2019. RESULTS: The study found a decrease in overall trauma admissions during the pandemic years (11,394 in 2020-2021 compared to 17,773 in 2018-2019). Notably, the average length of hospitalization increased during the pandemic, especially in rural areas (from 3.5 days in 2018-2019 to 5.5 days in 2020-2021 for head injuries). Male patients predominantly suffered from trauma, with a notable rise in female admissions for abdominal injuries during the pandemic. The maximal hospitalization days were higher in rural areas for head and neck injuries during the pandemic. CONCLUSIONS: The study highlights significant disparities in trauma care between urban and rural areas and between the pre-pandemic and pandemic periods. It underscores the need for healthcare systems to adapt to changing circumstances, particularly in rural settings, and calls for targeted strategies to address the specific challenges faced in trauma care during public health crises.
RESUMEN
Traumatic Brain Injury (TBI) represents a significant health concern, necessitating advanced therapeutic interventions. This detailed review explores the critical roles of astrocytes, key cellular constituents of the central nervous system (CNS), in both the pathophysiology and possible rehabilitation of TBI. Following injury, astrocytes exhibit reactive transformations, differentiating into pro-inflammatory (A1) and neuroprotective (A2) phenotypes. This paper elucidates the interactions of astrocytes with neurons, their role in neuroinflammation, and the potential for their therapeutic exploitation. Emphasized strategies encompass the utilization of endocannabinoid and calcium signaling pathways, hormone-based treatments like 17ß-estradiol, biological therapies employing anti-HBGB1 monoclonal antibodies, gene therapy targeting Connexin 43, and the innovative technique of astrocyte transplantation as a means to repair damaged neural tissues.

This study investigates the effectiveness of the Script Concordance Test (SCT) in enhancing clinical reasoning skills within paramedic education. Focusing on the Medical University of Lublin, we evaluated the SCT's application across two cohorts of paramedic students, aiming to understand its potential to improve decision-making skills in emergency scenarios. Our approach, informed by Van der Vleuten's assessment framework, revealed that while the SCT's correlation with traditional methods like multiple-choice questions (MCQs) was limited, its formative nature significantly contributed to improved performance in summative assessments. These findings suggest that the SCT can be an effective tool in paramedic training, particularly in strengthening cognitive abilities critical for emergency responses. The study underscores the importance of incorporating innovative assessment tools like SCTs in paramedic curricula, not only to enhance clinical reasoning but also to prepare students for effective emergency responses. Our research contributes to the ongoing efforts in refining paramedic education and highlights the need for versatile assessment strategies in preparing future healthcare professionals for diverse clinical challenges.
RESUMEN
The relationship between Toll-like receptor 9 (TLR-9) signaling and its involvement with Epstein-Barr virus (EBV) in gastric cancer (GC) is complex and currently under study. This research intended to understand TLR-9's role in certain T and B lymphocytes and the serum levels of TLR-9 in GC patients versus healthy subjects. The team explored links between these immune markers and various GC traits, such as histological grade, tumor progression stages, cancer types, and survival rates. Additionally, the research sought to find if EBV genetic material influences these immune reactions. Using flow cytometry, TLR-9 levels in different immune cells were analyzed. At the same time, the amount of TLR-9 in the serum was determined. The results showed GC patients had varied TLR-9 levels compared to healthy subjects, with specific cells showing noticeable changes. When grouped by GC attributes, key relationships emerged between TLR-9 amounts, the histological grade, progression stages, and cancer types. A notable finding was the connection between TLR-9 levels and EBV genetic presence, suggesting possible interactions between TLR-9 responses and EBV-related GC processes. Survival data also hinted at TLR-9's potential as a predictor linked to clinical traits. Overall, this research emphasizes TLR-9's complex role in GC's immune responses, pinpointing its interactions with particular cells, clinical features, and EBV. The study unveils a complex web affecting GC and paves the way for new treatment avenues targeting TLR-9 pathways.
RESUMEN
BACKGROUND: Medical simulation allows for the achievement of many educational goals and the continued education of some practical skills. The COVID-19 pandemic's restrictions have led to a major increase in dental education simulations. The aim of this study was to analyse the perspectives of academic teachers towards dental simulation, their concerns and evaluation of this teaching method, as well as their opinion on the use of medical simulation during the COVID-19 pandemic. METHOD: A focus study was conducted in a group of 5 academic teachers, comprising 10% of academic teachers of a Dental Faculty using simulation techniques. Prior to and during the COVID-19 pandemic, the interviewed teachers had expertise with medical simulation in dentistry education methods. A facilitator used pre-planned, open-ended questions about the use of simulation in dentistry also with regard to the COVID-19 pandemic period. The group discussion has been managed, monitored, and recorded. The data analysis model was based on Braun and Clarke's six phases of thematic analysis. Five thematic domains/fields were evaluated: (1) Simulation as a didactic method; (2) Simulation during COVID-19 pandemic; (3) General observations and expectations with regard to simulation; (4) Teachers in simulation; (5) Concerns in relation to simulation. Two researchers analysed the data. RESULTS: Based on interviewed teachers' perspective the simulation allows students to learn basic and complex skills providing the repeatability of the procedures performed. During Covid-19 the simulation methods undoubtedly filled the gap in the training of future dentists. However, interviewed teachers pointed out the high cost of the methods dictated by the need to prepare the simulation environment at a high level, in order to reflect the real clinical situation. CONCLUSIONS: The use of simulation methods requires adequate preparation of academic teachers, continuous education and updating of knowledge in the field of medical simulation. The COVID-19 pandemic significantly influenced the growth of dental education simulation techniques as well as staff knowledge of the usage of medical simulation.

The coagulation and immune systems, two vital systems in the human body, share intimate connections that fundamentally determine patient health. These systems work together through several common regulatory pathways, including the Tissue Factor (TF) Pathway. Immune cells expressing TF and producing pro-inflammatory cytokines can influence coagulation, while coagulation factors and processes reciprocally impact immune responses by activating immune cells and controlling their functions. These shared pathways contribute to maintaining health and are also involved in various pathological conditions. Dysregulated coagulation, triggered by infection, inflammation, or tissue damage, can result in conditions such as disseminated intravascular coagulation (DIC). Concurrently, immune dysregulation may lead to coagulation disorders and thrombotic complications. This review elucidates these intricate interactions, emphasizing their roles in the pathogenesis of autoimmune diseases and cancer. Understanding the complex interplay between these systems is critical for disease management and the development of effective treatments. By exploring these common regulatory mechanisms, we can uncover innovative therapeutic strategies targeting these intricate disorders. Thus, this paper presents a comprehensive overview of the mutual interaction between the coagulation and immune systems, highlighting its significance in health maintenance and disease pathology.

Gastric cancer is one of the five most common types of cancer worldwide. Due to the heterogeneous course and the involvement of many risk factors, its treatment and diagnosis is an important challenge for modern medicine. Recent studies have emphasized the i role of Toll-like receptors (TLRs) expressed on selected cells of the immune system in the pathogenesis of gastric cancer. The aim of this study was to determine the prevalence of TLR2 on T lymphocytes, B lymphocytes, monocytes, and dendritic cells in patients diagnosed with gastric cancer, with particular emphasis on the stage of the disease. Based on the obtained results, we have shown that patients with gastric cancer are characterized by a higher percentage of all tested populations of peripheral blood immune cells expressing TLR2 in relation to patients from the control group. Moreover, a detailed analysis of the collected results showed a significant link between TLR2 and the stage of the disease.

Background: Education with the use of medical simulation may involve the use of two modalities: manikins or standardized patients (SPs) to meet specific learning objectives. We have collected students' opinions about the two modalities which can be helpful in planning and evaluating the curriculum process. Although reviews or comparisons of student opinions appear in the literature, it is difficult to find a scale that would be based on a comparison of specific effects that can be obtained in the educational process. In order to fill this gap, an attempt was made to construct a questionnaire. Methods: An experimental version of a questionnaire measuring the final-year students' (273) opinions about the effectiveness of both simulation techniques has been designed on the basis of semi-structured interviews. They were conducted with 14 final-year students excluded from the subsequently analyzed cohort. The scale has been completed, tested and validated. Results: The authors developed a 33-statement questionnaire which contain two scales: teaching medicine with the manikins and with the SPs. Two factors were identified for each scale: Doctor-patient relationship and practical aspects. The scales can be used complementary or separately, as the article reports independent statistics for each scale. The Cronbach's alpha coefficient for the manikin scale is 0.721 and for the SP scale is 0.758. Conclusions: The questionnaire may be applied to medical students to identify their opinions about using manikins and SPs in teaching. It may have an important impact for planning curriculum and implementing particular modalities in accordance with the intended learning objectives.

Background: Fenestrations are rare, but well-known, vascular variations of the cerebral arteries. They are mostly incidental, asymptomatic angiographic findings and might precipitate vascular lesions such as AVM, aneurysmal dilatation, or even ischemic symptoms. However, association between arterial fenestration and brain aneurysms has not been clearly established. Objective: To evaluate whether incidence of arterial fenestrations are associated with brain aneurysm development and investigate the prevalence and most-common localizations of arterial fenestrations of the human brain. Design: Case−control study. Setting: All patients examined by CT angiography in University Hospital No. 4 in Lublin from 2009 to 2019. Patients: Each patient showing at least one cerebral aneurysm was included in the case group and each patient without cerebral aneurysm on CT angiography was included in the control group. Measurements: CT angiography examinations were conducted using the standard protocol used in the 1st Department of Radiology, Medical University of Lublin, Poland. The database and statistical research were conducted by use of the Statistica software (ver. 13.3, Tibco Software Inc., Palo Alto, CA, USA). Results: A total of 6545 CTA examinations were included in the study. Most of the aneurysms were located on the MCA: 629 (38.59%), ICA: 466 (28.59%) and AComA: 192 (11.78%). Cerebral arterial fenestration showed a non-statistically significant elevated risk for brain aneurysms in the entire study population (OR: 1.157; 95% CI: 0.826−1.621; p = 0.39). Among 6545 cranial CTA examinations, cerebral vessel fenestration was found in 49 of them, which constituted 0.75%. The most common vascular fenestrations were those located in the ACA (30.61%), BA (30.61%) and AComA (22.45%), while other fenestrations occurred infrequently. There were no significant differences in the age of patients in the individuals with vascular fenestration (p > 0.05). VA fenestration was slightly more common in men (16.67%) than in women (5.41%). However, these differences were not statistically significant (p = 0.216). Limitations: Our study has several limitations, including selection bias regarding examined population. Second, we assume that the total number of fenestrations detected in our study was underestimated due to the limitations of the CT method in comparison to other radiologic modalities. Conclusions: Cerebral arterial fenestrations are rare vascular malformations. The ACA is the most common localization of fenestrations, followed by BA and AComA. Fenestrations of cerebral arteries insignificantly increase the risk of cerebral aneurysm formation. Further prospective studies are necessary to make this association more precise.
RESUMEN
BACKGROUND: Toxic epidermal necrolysis (TEN) patients require multi-directional and multi-disciplinary treatment. In most cases, they are hospitalised at intensive care units and require multi-directional, burn-complication preventive care. Choosing the most appropriate treatment option might be troublesome even when predicting scores are used. SCORTEN is the most renowned prognostic score for TEN patients, however, there are some data indicating that the accuracy of this test may be limited. The credibility of not just the predicted mortality risk, but also componential laboratory results and clinical features subject to debate. The aim of this study was to evaluate the efficacy and credibility of SCORTEN in clinical practice, on proprietary material. METHODS: A retrospective analysis of 35 patients with diagnosed in histopathology TEN was performed. The inclusion criteria were as follows: day of submission before 5th day from the onset of the symptoms, full protocol of plasmaphereses and IVIGs according to our scheme. Our protocol includes cycle of plasmapheresis with frozen fresh plasma twice daily for the first 2 days following admission, and once daily for the subsequent 5 to 7 days. IVIGs were administered after the first two sessions of plasmapheresis, for 4 to 7 days. The dosage was calculated according to body weight, at 0.4 to 0.5 g/kg per dose. RESULTS: The sensitivity of SCORTEN for the analysed cohort was 100%, with a specificity of 24%. The estimated death was 41,9%, while the actual death rates were 12,5%. Our protocol improved the survival, OR = 26,57, RR = 6,34, p = 0,022. Decrease in mortality was caused by a combined treatment protocol we use- plasmaphereses with IVIGs. No independent risk factor was significant in death evaluation. CONCLUSION: Our data suggest that the scoring system for predicting death among TEN patients are reliable when they are high. New prognostic factors should be found to improve the evaluation of patients with low SCORTEN.

Gastric cancer remains one of the most commonly diagnosed cancers in the world, with a relatively high mortality rate. Due to the heterogeneous course of the disease, its diagnosis and treatment are limited and difficult, and it is associated with a reduced prognosis for patients. That is why it is so important to understand the mechanisms underlying the development and progression of this cancer, with particular emphasis on the role of risk factors. According to the literature data, risk factors include: changes in the composition of the stomach and intestinal microbiota (microbiological dysbiosis and the participation of Helicobacter pylori), improper diet, environmental and genetic factors, and disorders of the body's immune homeostasis. Therefore, the aim of this review is to systematize the knowledge on the influence of human microbiota dysbiosis on the development and progression of gastric cancer, with particular emphasis on the role of the immune system in this process.
RESUMEN
BACKGROUND Accurate estimation of burn depth is crucial for correct treatment decision making. Bromelain-based enzymatic debridement (ED) may improve clinical assessment of burn depth. Laser Doppler imaging (LDI) provides a valuable indicator of burn depth by analyzing microcirculation within tissue beds. This study aimed to evaluate bromelain-based enzymatic debridement combined with laser Doppler imaging and healing of 42 wounds in 19 patients with mixed second- and third-degree thermal burns. MATERIAL AND METHODS We included 42 wounds in 19 patients with mixed deep dermal and full-thickness thermal burns. All patients were treated with eschar-specific removal agent for ED. The perfusion of each wound after ED was assessed using LDI. Healing time was estimated by 2 experienced burn surgeons and marked by the observation of epithelization. The usefulness of the LDI performed after ED in predicting healing time was estimated. The findings were analyzed to determine a cut-off value for LDI that indicates if a burn will heal spontaneously. RESULTS We observed that burn wounds with higher mean perfusion healed faster. The analysis showed a strong relationship between perfusion after ED and healing time (Spearman rank correlation coefficient=-0.803). A mean perfusion greater than 296.89 indicated that the wound could heal spontaneously and does not require skin grafting. CONCLUSIONS LDI examination of an already debrided wound allows for a reliable assessment of perfusion at an early stage of treatment. The use of a safe and effective debridement method in conjunction with a non-invasive diagnostic tool could improve burn management.

INTRODUCTION: Early eschar removal is the standard management of burns. The goal is to remove all of the necrotic tissue and render the wound suitable for healing or skin grafting. The enzymatic debridement of burn wounds allows for minimally invasive removal of burn eschar. The aim of the study was to describe and compare the demographic characteristics, surgical treatment and outcomes of patients treated with Nexobrid® with patients who had standard surgical excision. MATERIAL AND METHODS: A retrospective review was conducted on children who underwent enzymatic debridement. The study group was compared with children treated with the standard of care (SoC). RESULTS: Twelve children (mean age 8 years, range 3 to 15 years) with mixed deep dermal and full thickness burn wounds were treated with Nexobrid®. The mean size of the burns was 29% TBSA. The median percentage TBSA debrided using Nexobrid® was 15% (range 2-27%). In a clinical assessment, enzymatic debridement was effective in removing dead tissue in a single application. No adverse reaction to Nexobrid® and serious complications after enzymatic procedure were recorded in the study group. The estimated relative risk of the need for reconstructive procedures decreases 3.5 times for the study group (RR 3.5, 95%CI 0.9-13.5, p = 0.089). CONCLUSION: The bromelain-based enzymatic method offers a good and safe debridement option to improve the treatment and life quality of children with severe burns. The main outcome of interest was the number of reconstructive procedures due to scar contractures, which was reduced in the group treated enzymatically compared to the SoC-treated children.
RESUMEN
The high cost of biofabricated titanium mesh plates can make them out of reach for hospitals in low-income countries. To increase the availability of cranioplasty, the authors of this work investigated the production of polymer-based endoprostheses. Recently, cheap, popular desktop 3D printers have generated sufficient opportunities to provide patients with on-demand and on-site help. This study also examines the technologies of 3D printing, including SLM, SLS, FFF, DLP, and SLA. The authors focused their interest on the materials in fabrication, which include PLA, ABS, PET-G, PEEK, and PMMA. Three-dimensional printed prostheses are modeled using widely available CAD software with the help of patient-specific DICOM files. Even though the topic is insufficiently researched, it can be perceived as a relatively safe procedure with a minimal complication rate. There have also been some initial studies on the costs and legal regulations. Early case studies provide information on dozens of patients living with self-made prostheses and who are experiencing significant improvements in their quality of life. Budget 3D-printed endoprostheses are reliable and are reported to be significantly cheaper than the popular counterparts manufactured from polypropylene polyester.
RESUMEN
Burns are one of the most common causes of home injuries, characterized by serious damage to the skin and causing the death of affected tissues. In this review, we intended to collect information on the pathophysiological effects of burns in pediatric patients, with particular emphasis on local and systemic responses. A total of 92 articles were included in the review, and the time range of the searched articles was from 2000 to 2021. The occurrence of thermal injuries is a problem that requires special attention in pediatric patients who are still developing. Their exposure to various burns may cause disturbances in the immune response, not only in the area of tissue damage itself but also by disrupting the systemic immune response. The aspect of immunological mechanisms in burns requires further research, and in particular, it is important to focus on younger patients as the existence of subtle differences in wound healing between adults and children may significantly influence the treatment of pediatric patients.
